TensorFlow serving

edit

When flow this blog(https://streamsets.com/blog/machine-learning-with-tensorflow-and-kafka-in-data-collector/), I got error like this on the Tenforflow processor:

 TENSOR_FLOW_02 - Error loading saved model : org.tensorflow.TensorFlowException: Op type not registered 'DivNoNan' in binary running on sdc-0. Make sure the Op and Kernel are registered in the binary running in this process. Note that if you are loading a saved graph which used ops from tf.contrib, accessing (e.g.) `tf.contrib.resampler` should be done before importing the graph, as contrib ops are lazily registered when the module is first accessed.

Anyone has got it worked for you? BR/Liyi
